#7 Cannot find SWIG. Python module cannot be built.

OK, thanks. I installed SWIG using homebrew, and running ./configure CPPFLAGS="-I /Users/sm2286/anaconda3/include/python3.6m" tells me that Python support is now enabled. Next I configured my PYTHONPATH to find loris, and it works! So far I haven't found any errors using Python 3.

Hi there,

I'm trying to install Loris and link it to my Python installation. I'm using anaconda Python 3.6. I located the header file (I think) here:/Users/smathias/anaconda3/include/python3.6m/Python.h

I then ran ./configure CPPFLAGS=-I/Users/smathias/anaconda3/include/python3.6m/Python.h

#6 Python support disabled on install - OS X 10.6.8

I'm stumped. The library is clearly present and usable.
Try running configure with the argument --without-fftw
Hopefully, this will get you running, I'm sure you're bored with this problem by now!

I would have settled for just the shell output, but this is much better. It shows clearly that fftw library and header are found, and found to be usable, at configure time. Doesn't really tell us what's wrong when it goes to link loris-analyze (which, btw, is completely separate from the Python module, so this problem might not even be interesting, except that if the build won't complete, you can't get it to install the Python module).

Can you type

ls /usr/local/lib | grep fftw

in a shell and let know what it says? I assume that you are letting homebrew install everything in /usr/local as it usually does. Let's see what it put there. I have one more hunch.

you could also just try running configure with the argument --without-fftw

Loris can get by without it.

Hmmm. If configure succeeded, then either it found FFTW, or decided to build without it. Evidently, it found it, in your case. So why can't it link against it?.... I wonder if there's something funny about the way that homebrew installs it. Can you post the lines in the configure output pertaining to fftw? They are right after the line

PYTHONPATH is used by the Python interpreter to find stuff like Python modules (when you get it to build, you're going to need to check that the loris module is installed in your PYTHONPATH).

configure/make and your compiler don't know anything about PYTHONPATH. There's a number of ways to tell configure where the header is. CPPFLAGS is fast and easy. But PYTHONPATH is not for that.
